+
+## Dataset Structure
+
+The dataset is structured as follows.
+
+### Subsets
+
+The dataset has one subset:
+
+- `default`: the default dataset.
+
+### Splits
+
+The dataset is divided into two splits:
+
+- `train`: the training split, consisting of 10,000 rows.
+- `test`: the test split, consisting of 1,000 rows.
+
+### Columns
+
+Each row in the dataset consists of the following columns:
+
+- `X`: the input value of the function f.
+- `y`: the value of the function f at X.
+- `coefficients`: the coefficients of the polynomial function f.
+
+### Data
+
+The dataset contains the following data:
+
+| Column       | Shape   | Type    | Range   |
+|--------------|---------|---------|---------|
+| X            | (100,)  | float   |         |
+| y            | (100,)  | float   |         |
+| coefficients | (3,)    | float   | [-1, 1] |
